Marked the outer edges of the bezel on the gunbody.
Then I marked the outer edges of the bargraph.
Used the vise to keep it steady and drilled four small holes with my Dremel.
Drilled the holes so that I wouldn't cut to much.
Used the Dremel once more, used these cut off plates
Worked like I wanted and it cut nicely into the resin
Used the Dremel again and removed a little more at the top, before I removed the rest of the resin with a wedge and a mallet.
Then some more Dremel work to remove what was left...
...but used the straight file to level it out and make sure it would fit, without the hole being to big
Prepped the last pieces for the gun (sanded, primed and painted)
And attached the screws for the banjos on the gun.
Drilled with 3,2mm and then used a 4mm tread to make the screws attach without glueing them (will attach with epoxy later, but knowing that everything fits properly before I glueing makes it feel more durable).
Attached the instrument panel
Attached it by drilling the readymade holes and used 4mm screws. It sits really firmly, but I'll add some epoxy to keep it in place all the same:
Had to make a little more room for the spacer and nut on one of the screws.
Also opened up the hole for the tube
Remember to use protection when sanding, kids.
Now you know. And knowing is half the battle, heh heh
